2020 IL App (1st) 171273-U
Ill. App. Ct.2020Background:
- Timothy Mobley was convicted after a 1994 jury trial of first-degree murder, felony murder, and (aggravated) kidnapping for the 1992 death of Kristin Ponquinette and sentenced to an extended 90-year term.
- Key State witness Venus Becom testified about events at the playground and acknowledged she received a deal: juvenile charges would be reinstated and the State would recommend probation in exchange for her testimony; she also testified she was not charged for soliciting sexual acts.
- Years later Mobley obtained an affidavit from ex-officer Charles Hill asserting that in 1993 Hill arrested Becom for suspected cocaine possession, but the State declined to prosecute because she was a cooperating witness and her father was a CPD officer.
- Mobley moved for leave to file a successive postconviction petition alleging a Brady violation (the State suppressed Becom’s uncharged drug arrest/impeachment); the trial court denied leave for failure to show cause and prejudice.
- The appellate court affirmed, holding Mobley failed to show the undisclosed evidence was material/prejudicial given (1) the jury already heard impeachment about Becom’s deal and initial silence, and (2) other inculpatory evidence (e.g., Carpenter’s written statement) could sustain the verdict.
Issues:
| Issue | Plaintiff's Argument (People) | Defendant's Argument (Mobley) | Held |
|---|---|---|---|
| Whether Mobley showed cause and prejudice to obtain leave to file a successive postconviction petition based on a Brady claim | Mobley has not shown prejudice — the alleged impeachment (Becom’s drug arrest) was not material and would not have changed the verdict | The Hill affidavit shows the State suppressed impeachment evidence that would have undermined Becom’s credibility and thus warrants successive review | Denied — Mobley failed to show the required prejudice under the cause-and-prejudice test; leave to file successive petition was properly denied |
| Whether Becom’s alleged uncharged 1993 arrest was Brady-material impeachment evidence | The jury already knew Becom received benefits and delayed disclosure; additional impeachment was cumulative and immaterial | The undisclosed arrest would have provided further impeachment of Becom and was therefore material to guilt or punishment | Held not material — cumulative impeachment would not have reasonably changed the outcome given other evidence implicating Mobley |
